Open the CIPO recordAbstract From the Canadian patent
In a coin mechanism for a vending machine the, inner face of the coin mechanism body is provided with a raised edge over which the coin projects slightly. As the coin mechanism is rotated, the coin travels along this raised edge. A portion of the raised edge is ramped inwardly, so that the coin is separated from the coin receiving recess with an axial force, thereby overcoming any attempt to circumvent the coin mechanism by adhering the coin to the coin receiving recess using tape or glue.

Why it's free to use
- Filed February 24, 1993 and granted January 21, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 24, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 24, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
